william puts 7 gallons of gas in his car and pays $28 he wants to know how many gallons he can buy for $40 at the same rate
how can you find the unit given the information in the table?
cost 28
gas 7
cost ? number of gallons
To find the cost per gallon, you can divide the cost by the number of gallons. In this case, the cost is $28 for 7 gallons, so the cost per gallon is $28 / 7 gallons = $4 per gallon.
To find out how many gallons William can buy for $40 at the same rate, you can divide the total amount he wants to spend by the cost per gallon. In this case, William has $40 to spend and the cost per gallon is $4, so the calculation would be: $40 / $4 per gallon = 10 gallons.
Therefore, William can buy 10 gallons of gas for $40 at the same rate of $4 per gallon.
how much does 1 gallon of gas cost? find the unit rate
To find the unit rate for 1 gallon of gas, you can divide the total cost by the number of gallons purchased. In this case, the cost is $28 for 7 gallons.
So, the cost per gallon is $28 / 7 gallons = $4 per gallon.
Therefore, 1 gallon of gas costs $4. This is the unit rate for 1 gallon of gas at this particular gas station.
how can you use the unit rate to find the amount of gas for any cost?
cost ? unit rate = number of gallons
To find the number of gallons that can be purchased for any cost using the unit rate, you can use the formula:
Cost ÷ Unit rate = Number of gallons
Given that the unit rate for the gas is $4 per gallon, you can use this formula to calculate the number of gallons you can buy for any given cost.
For example, if you want to know how many gallons you can buy for $40:
$40 ÷ $4 per gallon = 10 gallons
So, for $40, you can buy 10 gallons of gas.
This formula allows you to quickly calculate the number of gallons you can purchase for any cost using the unit rate of $4 per gallon.
